Nothing Is Better Than Copy or Move

Explore the intricacies of C++ move semantics and copy elision in this ACCU 2018 conference talk. Delve into the evolution of object creation optimization from C++98 to C++17, examining worked examples and practical implications. Learn about temporary materialization, potential pitfalls in clever coding, and the rules governing special members. Compare copy and move operations, understand MSVC x86/x64 conventions, and gain insights into efficient argument passing and return value handling in functions. Discover why sometimes not creating an object at all can be the most efficient approach in C++ programming.
